Our wrenches feature a high carbon steel body with a low carbon steel rod handle. Special commercial tempering gives optimum strength to the wrench fingers. The malleable handle will flex if excess torque is applied, to avoid damage. Our wrenches are not unbreakable, but they are pretty close!

#NW-130 wrench has a .187" slot in a .29" shaft to fit the tapered nipple recess found on 1858 Remington revolvers. The majority of Remington reproductions use six (6) #PIR-S stainless steel nipples for M6-.75mm nipples. The temper blue color will vary due to the heat treating process.

Use this wrench with your Ruger Old Army revolvers, when installing our #PRA-S nipples. This wrench fits our new Ruger nipples perfectly, but is too snug to fit the factory hex nipples.

Revolvers are made in batches, in Italy, to the importer's specifications. Nipple size can vary within a brand, from lot to lot. Generally, the 1858 Remington copies use the metric nipple. Generally, the Colt replicas made after 1980 use the 12-28 nipple. But we have seen variations.

Stuck nipple? Try soaking the cylinder in penetrating oil for a few weeks, and be gentle using this wrench. Once removed, use our #BC-CTL Choke Tube Lubricant to prevent the nipple from ever becoming stuck.
